Comparative Study of Automatic Acquisition Methods of Image Processing Procedures

Two image processing expert systems, IMPRESS[1] and IMPRESS-Pro[2] have already been developed by our research group. These systems automatically generate image processing procedures from sample pairs of an image and a sketch representing an object to be extracted from it. Automatic acquisition of the image processing procedure is a kind of knowledge discovery process, because an image processing procedure which can extract a figure like the given sketch from the image can be regarded as a representation of knowledge about the object in the image. In this paper, we examine above two expert systems comparatively from the knowledge discovery viewpoint.
